What is this Corridors of Unmotorized Movement all about? Are they intended to form a useful network? This article raises more questions in my mind than it answers.

"Officials in Mexico City have been ordered to leave their cars behind and cycle to work once a month.

The new city regulation that has just come into force is aimed at reducing traffic and pollution in one of the most congested cities in the world.

About four million cars travel every day through the city of more than 18m people - and officials say their aim is to cut pollution as well as disease.

Once a month will only cut car use by 1/28. Once a week would be a better goal.

IMO, a better plan would be to have two bus lanes and one bike lane for each car lane. Strictly enforced.

It's ironic that governments of crowded cities never hit on the obvious answer to gridlock and pollution: Ban car use or strictly curtail it. Put in electric trains or at least hybrid buses to take up the slack. I guess this answer is too simple to appeal to policy makers?

Like many cities if you can design the majority of your daily life around the city center and transit you'll in good shape. The Mexico City Metro is very efficient and goes to all corners of the city, including the huge leafy university at the south end.

I agree about biking though. Other than a few wide boulevards and the green areas of Chapultapec you'd be in for a major thrill ride heart stopper.

I've never been there and have had the impression that the air pollution is a bigger worry than crazy drivers. The article states that the mayor is biking from his home in the south to the center city. It also reads like they're creating unmotorized routes. I suspect that it is a matter of we outsiders not understanding the traffic conventions and seeing danger where there isn't much. It also seems that of all the workers forced to bike once per month many will be like me and realize that biking is so much better that the car gets dumped. A 3% reduction in car trips is a step in the right direction because it results in a huge increase in the numer of people who discover as a fact that they can get around without a car and then will be more agreeable to other car free type initiatives.

I once went to an exhibition focused on Mexico City at P.S. 1 in Queens. The cityscape photos were revealing. You know Mexico City is built on a dry lake bed, it is completely flat and huge. HUGE! 10 million people and the sprawl goes forever, the city is like L.A. on steroids.

Back to topic, a few thousand city officials commuting by bike 12 times per year will make no significant difference at all. This gesture is purely symbolic. And given the local conditions, I'd say its downright hazardous.
